CHARLES E. RECTOR, OF NEW YORK, N. Y.

WHISTLE.

SPECIFICATION formingpart of Letters Patent No. 247,850, dated October 4, 1881 Application led August 15, 1881. (No model.)

To all whom it may concern Be it known that I, CHARLES E. RECTOR, a citizen ot' the United States, residing' at New York, in the county of New York and State r; of New York, have invented certain new and useful Improvements in \\`histles; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which fornia part of this specification.

The object of this invention is to improve that patented to me June 21, 1881, numbered 243,158, which is for improvements in toy whistles, and in which the bulb or elongation ofthe tube beyond the air-exit is placed at an angle to the tube.

By practical experience it is found that it is not necessary to make a bend or an angle at or near the air-enit; and this improvement consists in constructing the whistle-tube and its bulb or elongation on a straight line, as will be fully described and shown.

In the drawings, Figure 1 represents the toy with its bulb and tube in aline; and Fig. 2 represents the toy tube with an elongation instead of the bulb, as a moditication of the construction seen in Fig. l.

A represents a tube of any desired length or diameter, depending upon the use to which it is applied, and upon one end of the tube is formed a bulb or other enlargemant, or an elongation, B, which-is closed or air-tight.

C is a neck or contracted part ot' the tube A, near the bulb or elongation B, and in said neck is an air-aperture or air-exit, c. The depression in the tube opposite said air-exit c serves to direct a portion of the air injected against the edge of the tube at the outlet, thus causing it to produce the sound emitted.

Air being forced into tube A at the open end a, passes freely through the tube to opening c, where some continues on to ll the bulb or elongated part B, and is compressed therein, while the remainderis forced out through opening c in contact with that which is compressed in the bulbB trying to escape, and the edges of the opening@ cause a shrill and sharp whistle, varying in sound with the amount of force by which the air is driven through the tube.

The toy whistle, when constructed without an angle at the neck, can be used for the same purposes and in the same way contemplated in said Patent No. 243,158. and constructed from the same material described therein. When used as a toy the lungs of the person using it will force the necessary amount of air to make a shrill whistle, but when it is used for other purposes, where a louder sound is to be given, and by a larger tube, the requisite amount of air must be forced into and through the tube by any convenient and available power for such purpose. As a toy it is cheap and pleasing to the young, and when made of glass tubing the glass can be colored to suit the fancy, in as many different colors as nature provides, and as many changes of those as there are different shades of color, and a combination of any number ot' the colors or shades as may be desired.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A whistle composed of the tube A, having open end a, neck C, having air-exit c, and bulb or elongation B, all on straight central or axial line, substantially as and for the purposes described.

In testimony whereof I affix my signature in presence ot two Witnesses.

CHARLES E. RECTOR.
